What is the typical shelf life of PH test strips? I would appreciate the advice of experts. .
The shelf life is related to the conditions of storage; under normal circumstances it is around 2 years, and it can last longer if stored properly. Storage conditions: 1. Room temperature, dry ； 2. Sealing ； 3. Protect from light
-- There should be instructions on the packaging; following those instructions should be fine. --
Is it possible for them to remain in good condition and be usable for 3 to 5 years? ?
It can be calibrated with instruments; the test strips I’m using right now have passed their useful life
One is related to your storage conditions, and the other is related to the type of test strip; generally, it’s around two years.
